    VCCRTC ok
    RTCRST# ok
    ATX_5VSB ok
    SIO_3VA ok
    3VDSW ok
    DPWROK ok
    SLP_SUS# ok
    VSB_ENABLE# ok
    5VDUAL ok
    3VSB showing 4.17V
    PCH_1P8_VSB ok
    PCH_VCCIN_AUX ok
    RSMRST# No voltage

    this all voltages are ok but RSMRST# voltage is missing i did try to re program bios and change io but same condition and have another problem . this motherboard 3vsb voltage little bit high . showing 4.17V. i did change regulator ic but same condition anyone have a solution ?

          after checking all ive decided to flash the bios.
          Now the DC jack glows ,after checking the first reset signal the RSMRST# IS ov

          32,768KHZ is present at Y5 on oscilloscpoe
          RTCRST# has 3.3v @ CLRP2
          RSMRST# 0v @ pin 100 f ec
          ON/OFFBTN @ pin 32 has 3.3v when triggered goes 0v and goes 3.3v if released
          PWRBTN_OUT# @ 117 has 3.3v if triggered the switch doesnt goes to 0v .

          EC_ON @ 102 -3.3v

          Weired MSI B560M PRO (MS-7D20) - not starting with 11-th gen. CPU, 10-th gen. OK
          by DynaxSC
          Hi,

          I have a very weired problem with MSI B560M PRO (MS-7D20), board is upgraded to the latest BIOS version v1.9.

          The board is normally starting with 10-th gen. CPU, ie. Intel Comet Lake i5-10600K and Celeron G5905.

          However if I install a 11-th gen. Rocket Lake i5-11600K the board powers up, but is immediately stuck on CPU LED, not progressing further. Debug card shows FF, and after restart with long short of Power Button: FE, which is as usually of no help (Reserved for future AMI error codes).

          According to MSI compatibility site the board supports...

          820-02020 PPBUS_AON missing
          by ugamazing
          Board had no history of liquid; unsure of drop history, but no signs of damage of any kind worth noting.

          Charger sitting at 5v/0a. PPBUS is at 1.9v-0.9v steady cycle (peaks, drains, loops). Confirmed CHGR_EN_MVR is missing, but DCIN was reaching ISL just fine, so replaced ISL--no change at all. Confirmed pp3v8_aon is also missing--and being unsure *exactly* which signal appears first (or if they are simultaneous), I inspected PMU/U8100 area and found no shorts, but also found PP3V8_AON_MPMU_ISNS_VIN missing (not shorted). Replaced U8100 just in case (have had them fail in weird ways),...

          Apple NVIDIA AGP GeForce 6800 GT Dual Link DVI+DVI outputs 603-6338 missing caps!
          by jpreza
          Hi everyone,

          I recently acquired this card from a seller who was selling a PowerMac G5 for parts. He mentioned that the video card was probably broken too.

          Upon closer inspection, I can tell the reason why it won't work: it's missing a bunch of CAPS! (it's also missing an inductor - 1.0uH).

          It's a nice card as it's one of the few AGP cards that will support 2560 x 1600 resolution on a PowerMac G5 using a 30" Cinema Display.

          Looking at the card, it appears to be missing the following:

          1x 1.0uH inductor - orange square
          2x...
